Maze of Realities: Flower of Discord

You're a missing person investigator. Your niece, along with her expedition members, has disappeared in the mountains of Greenland. While looking for them, you open a portal to another world. But soon it turns out that there's not only one world, but three: Arcalium, Atlantis, which is also known as the Underwater World, and the Parallel World!

The balance between them depends on the magic flower called Anima that grows in Arcalium — its pollen produces the oxygen that is vital for Atlantis. But a stranger from the outer world stole it... You need to find the intruder and return Anima!
